RE: ultra stick lite engine choice
Mine was with CH Ignitions electronic ignition. I never run magnetos. I like all the benefits of electronic ignition, or Gas/Glow.
My Ultra Lite Stik also had a smoke system. It was a lot of fun. To replace it, I bought a Giant Big Stik. I like it, but the aerobatics were a little more lively with the Ultra Lite Stik.
